Set ConnectInBackground based on request

Set the QNetworkSession attribute to match the QNetworkRequest that
triggered it.
Currently if there are a mix of normal and background requests queued
and background connections are not allowed by policy:
 - background requests at the head of the queue should fail
 - first foreground request should successfully start a connection
 - remaining requests succeed regardless of background attribute
